There are four different co-op attacks in this game and the majority are utterly useless. To use the attacks you have to build up your meter at the bottom of the screen which doesn't take long and then one of the players has to press X. Whatever weapon the player pressing X had equipped will equip to co-op varient on both of you. Once you have the co-op weapon equipped it will last around 30 seconds which is more than enough to kill 10 people given the rate at which this game throws enemies at you. When it is equipped you cannot leave your vehicle however you can cut it short by either one of you changing weapon.

Machine Gun upgrades to a more accurate version in which the bullets from each player ricochet off eachother creating a cone of fire. This is one of the only effective co-op attacks and the easiest to get 10 kills with. Simply fire as normal at enemies.

Flak Cannon upgrades to a sort of boomerang cannon which fires grenades that arc across the screen and return to your vehicle is they fail to collide with anything. If the two boomerangs from each player collide they create a large explosion. They seem to be drawn towards eachother which means if you are even slightly close to eachother they will explode in your face and no matter what your position they have a very limited range. They also seem to glide over infantry inflicting little damage.

The Flame Thrower upgrades to a constant wall of fire between your two vehicles. This is effective in the right situation but this rarely presents itself. Two players skilled in using this can decimate armies but without good coordination it leaves you vulnerable as you are unable to fire.

Freeze Cannon upgrades to a sort of ice rocket launcher which is by far the worst of the co-op attacks. It freezes things slower than the regular spray and if the two collide it cuts them short with no explosion. The only advantage is it has a marginally longer range than the spray but with the two rockets bumping into eachother it is highly undesirable.

Always aim for infantry if they are available and try to maintain a large distance between the two players for maximum efficiency with all four weapons. Hope this helps and feel free to comment.
